Static Black Holes and Iyer-Wald Entropy in Gravity
I. Díaz-Saldaña, J. López-Domínguez, Wilfredo Yupanqui +2
We investigate static, spherically symmetric black hole solutions in a class of higher-curvature gravitational theories described by a Lagrangian that depends on the Ricci and Kret…

Effective Improved-GUP Cosmology: Emergent FLRW Universe without a Bounce
Saeed Rastgoo, Wilfredo Yupanqui
We investigate the effective dynamics of a spatially flat FLRW universe coupled to a massless scalar field by applying the improved generalized uncertainty principle (GUP)-inspired…

Deformed algebra and the effective dynamics of the interior of black holes
Pasquale Bosso, Octavio Obregón, Saeed Rastgoo +1
We consider the classical Hamiltonian of the interior of the Schwarzschild black hole in Ashtekar-Barbero connection formalism. Then, inspired by generalized uncertainty principle…
